opponent spawned a 5/5 demon with haste menace and lifelink from a creatures exile effect. I had two minions on the board tiny bones which I confiscated from him and another 3/4 creature. When the demon spawned and attacked I was not allowed to block the creature with menace at all even though I had two creatures to block with. Both were untapped and no binding or bypass mechanics on the board. Cost me the game because it should have died to tinybones deathtouch but it bugged and wouldnt allow a block at all. No option what so ever. Just went straight thru. >.<
